Studies of Transverse Impact Damage in Composite Materials Using a Hopkinson Type Pressure-Bar Technique (1987),

摘要

Previous work on the transverse impact testing of fibre-reinforced plastics is briefly reviewed. A new apparatus, using a Hopkinson-type instrumented input bar, is described and results presented for low-velocity impacts on plain-weave reinforced epoxy laminates with either all-carbon plies, all glass-plies or various hybrid combinations of the two. Distinct differences are observed in the damage mechanisms for the various hybrid laminate lay-ups.
